Biceps are in a stronger position when the hands are supinated, but people with certain wrist or elbow problems may find the neutral grip more comfortable (which is why the UXS has close, neutral-grip pull up handles).

The hands should be supinated (palms facing back) for chin ups. If the palms are pronated (facing forward) you are doing a pull up. Rowing can effectively be performed with a variety of grips, depending on the equipment available and goals.

Vests, belts, and other ways of adding weight will be mentioned but will not be a major focus.

Low back exercises are going to be covered.

Other topics I’d like to see/suggest covered in that book are:
(1) why neutral grip for body weight row but palm-facing-forward for chic ups?,
(2) how to optimize use of a weighted vest with these “body-weight” exercises (like how to know when to add weight inserts over time?, and how to choose the best one-total-weight-fit-all-exercises-in-same-session vest weight instead of having to add or remove weight inserts for each individual exercise)?
(3) lower-back BODY-weight exercises that help prevent lower back pain from muscular (or other?) cause?

I understand if you do not wish to cover those. Just suggestions.

Thanks!

I recommend doing the exercises in order from harder to easier while alternating between different muscle groups unless you’re intentionally pre-exhausting. I will be covering this in detail in the bodyweight HIT book I’m writing.

Even if you split a workout up or do only a few exercises per day there is a lot of overlap in muscular involvement between exercises and a systemic effect which could interfere with recovery from previous workouts. Some of the cardiovascular and metabolic benefit would probably be lost by making the workouts too brief. Unless you work out at home or work at a gym or training studio and are there most days of the week you would also waste a lot of time traveling to only do one set.

Better to do one or two brief, full-body workouts per week than an exercise or two each day.

The proper training volume and frequency depends on your body’s response to exercise, your goals, and your schedule. As long as you are making good progress training twice weekly there is no need to cut back. Experiment, evaluate, adapt accordingly.

what criteria should be used over time to vary the order in which these body-weight exercises are performed?

thanks!

Thank you for all you blog posts and videos, they are great!
I want a UXS – so cool!

I have been doing a similar routine for a few months now, it is amazing what just 15-30 minutes a week can do.

What would be the pros and cons of splitting the routine up?
Squat one day, dips the next – etc. ?
Thank you.
